Clean energy through innovation

The world is using more energy than ever before, but most of it still comes from fossil fuels. We need to change course – and fast. This infographic explores if new technologies can put us on track for a clean energy future.

THE WORLD IS USING MORE ENERGY THAN EVER BEFORE. BUT MOST OF IT STILL COMES FROM
FOSSIL FUELS. WE NEED TO CHANGE COURSE—AND FAST. CAN NEW TECHNOLOGIES PUT US ON
TRACK FOR A CLEAN ENERGY FUTURE?
China currently has a quarter of the world's
renewable electricity capacity
Hydroelectricity is a renewable source
of energy, but not one that can be scaled
up sustainably. Flooding valleys for large
hydroelectric dams destroys wildlife
habitats and displaces people.

THE WORLD'S POPULATION HAS GROWN OVER THE LAST 50 YEARS. BUT SO HAS
THE ENERGY USED PER PERSON, LEADING TO HIGHER CO2
EMISSIONS.
THE PROBLEM ISN'T THAT WE'RE RUNNING OUT OF FOSSIL FUELS. THE WORLD
HAS OVER 50 YEARS OF OIL AND GAS AND 100 YEARS OF COAL LEFT. BUT WE
CANNOT AFFORD TO BURN THEM.

THE BIZARRE TECHNOLOGIES BEING ROAD-TESTED TODAY THAT COULD
ONE DAY MEET OUR ENERGY NEEDS
BIODIESEL FROM ALGAE
Algae are up to 50% oil and can produce 15
times more fuel per acre than oil palm. Biodiesel
from giant algae-ﬁlled ponds could one day
power jet aircraft.
GIGANTIC BATTERIES
Nuclear plants provide a constant stream of
backup power. But power demand fluctuates
over the day, so surplus energy is generated at
off-peak times. Enormous batteries could soon
store this energy and release it when needed.
HIGH-ALTITUDE TURBINES
Winds in the jet stream, 8-16km up, are on
average eight times as powerful as surface
winds. What if we could capture that energy?
Over 50 commercial projects are currently
working on it.
HALOPHYTE BIOFUELS
Today's biofuels compete with food crops for
land and fresh water. But salt-loving plants
called halophytes don't have this
problem—they can grow in deserts irrigated
with seawater—making them a promising
option for future biofuels.
ECOPARKS
Energy and industrial plants can be coupled
with each other as an ecosystem to minimize
energy, material waste and environmental
footprints. For example, surplus steam from a
power plant can be transferred to another
plant, or used to heat homes.
COULD WE EVER POWER THE WORLD
ON CLEAN ENERGY? YES—AND WE
COULD DO IT BY 2030.
POWERING THE WORLD ON CLEAN
ENERGY ALONE WOULD TAKE JUST
1% OF THE WORLD'S LAND AREA.
